-> ⚠️ Warning: `set` and `del` do NOT exist in Vue 3. We provide them as a workaround here, due to the limitation of [Vue 2.x reactivity system](https://vuejs.org/v2/guide/reactivity.html#For-Objects).
->
-> In Vue 2, you will need to call `set` to track new keys on an `object`(similar to `Vue.set` but for `reactive objects` created by the Composition API). In Vue 3, you can just assign them like normal objects.
->
-> Similarly, in Vue 2 you will need to call `del` to [ensure a key deletion triggers view updates](https://vuejs.org/v2/api/#Vue-delete) in reactive objects (similar to `Vue.delete` but for `reactive objects` created by the Composition API). In Vue 3 you can just delete them by calling `delete foo.bar`.

-```ts
-import { reactive, set } from '@vue/composition-api'
-
-const a = reactive({
-  foo: 1
-})
-
-// add new reactive key
-set(a, 'bar', 1)
-
-// remove a key and trigger reactivity
-del(a, 'bar')
